FIGJB BUILDING WITH A SUPPORTING WALL FRAME STRUCTURE AND WALL PLATES DETACHABLY SECURED THERETO The present invention relates to a building construction which is primarily intened to be used for erecting single family dwellings or bungalows but which may also be applied in connection with erecting of apartment buildings. The parts forming the building construction should also be usable for renovation.

The main object of the present invention is to provide a system of relatively simple parts, the number of parts being relatively small, in order to enable erecting of single family dwellings having a flexible design and interior. The parts of the building should be so simply de signed that they may be used in mass production so that they can be manufactured at a low price. Within the scope of the inventive idea, the parts of the building should be able to be joined together in such a simple manner that the erection of the building can be made by laymen.

Primarily the invention relates to a new wall construction of a building but the invention also embodies a roof construction having certain parts which are identical with parts used in the wall construction so that the walls and the roof may be constructed by the same standard elements. In line with the basic idea of the invention to provide an inexpensive building, there is also suggested a new method of laying the building foundation.

The characteristic parts and details of the building according to the invention are defined in the annexed claims. Some suitable embodiments of the building according to the invention and the standard elements required for erecting the building are shown in the accompanying drawings.

The form shown in FIG. 1 for moulding a foundation plate for the building according to the invention can be built in various sizes in the selected module system for the wall frame structure of the building. The purpose of the form is to make possible its re-use and that it may be moved from one building place to another in order to save costs for the moulding work.

The form in FIG. 1 comprises a frame of form parts 1 connected together and supported by vertically adjustable support members 2. The support members are in the form of adjustable screws and may be adjusted for bringing the whole form into a horizontal position. In order to adjust the vertical position of the form parts to bring them into the same plane, there is used a number of adjustment members 3, 4 located along the circumference of the form. each adjustment member being anchored in the ground at 5 and extending from this anchoring point in the form of two adjustable members 3. 4 for example screws having opposite threads at their two end portions and which are connected to an upper and a lower point on the form. The opposite sides of the form are connected with each other through prestressed rods 6 which serve as reinforcing members in the mould and also possibly a support for a reinforcing network 7. On the inside of the parts of the form are provided cover plates 8 for sealing the lower portion of the form against the underlying ground.

In the upper portion of the Figure is shown a section through the base plate when moulded. In its upper side are formed channels 9 for electric conduits, discharge conduits and other conduits.

Alternatively, the foundation of the building may in a known manner per se rest on poles which carry a beam structure. The beams are preferably of channel section and are open upwards so that they according to the invention may be filled completely or partly with sand so that the beams shall obtain a greater inertia in the position of use and thereby minimize vibrations in the building. This will result in a more rigid floor in the building in relation to conventional beams having relatively thin walls. In addition to a more rigid floor, the advantage is obtained that the beams will have a small weight upon transportation and so that the required weight and inertia will be reached not until the beams have been brought to the place of use.

On the foundation of the building is erected a wall frame structure of the construction shown in FIG. 2. The wall frame construction comprises a number of interconnected frames having a size which is standardized to a module system common for the whole build ing. Each frame is intended to receive an outer wall plate 5 and an inner wall plate 11. Both plates are of double walled construction having an intermediate layer of insulating material. Along the circumference of the plates is a projecting edge flange 12 which is intended to rest against the frame when the plate itself is inserted into the frame. Between the flange and the frame is a ceiling 14 which is shown more in detail in FIG. 12.

The size of the frames is preferably 3.0 m X 2.7 m. This size enables the wall plates to be handled by two men upon transport and erecting. The wall plates are secured to the frame by means of simple locking members which will be described more in detail in connection with FIGS. 11-15.

Each frame consists of a lower part and an upper part identical with the lower part and further of two mutually equal side parts.

The lower parts of the frame are shown in FIG. 3 and are denoted by numeral 15. Each lower part and upper part. respectively, consists of a double beam comprising two parallel mutually spaced single rails 16, 17 which are interconnected by means of distance members 18 preferably of a material having a low heat transmission capacity in order to prevent the formation of cold bridges.

At the ends of the lower parts and the upper parts, respectively, there are guide members 19, 20. When the lower parts are mounted with their ends against each other. the guide members 19, 20 of the two lower parts form together a rectangular guide member which is composed of two guide members 19, 20. In order to connect the lower parts and the upper parts of the frame with each other. each frame side member comprises two separate uprights 21, 22 which in the example shown comprise tubular members with rectangular cross section, each upright being provided at its ends to engage the respective pair of guide members at the lower part and the upper parts of the frame, respectively.

The uprights 22 are provided with edge flanges 23 which are intended to cooperate with locking members to be described in connection with FIGS. 11-15.

In FIG. 5 are shown two lower parts 15 forming an angle with each other in a corner of the wall structure, the ends of the lower parts being adapted to be coupled together by means of a connecting member 24 which is provided with guide members 25 for engaging the guide members 25, 26, 27 of the lower parts. The guide member 26 and associated guide members of the lower parts are coupled together with the tubular member 28 whereas the guide member 27 and adjacent guide member of the lower part 15 are coupled together by means of a rectangular tubular member 22 and a corresponding tubular member, not shown, is used for coupling together the guide member 25 and the guide member 20 of the adjacent lower part. How this coupling is made will be understood from FIG. 6.

FIGS. 7 and 8 show how the lower parts and the upper parts, respectively, of the frames are coupled together at an interior corner. In this case the lower parts and the upper parts of the frame are obliquely cut at an angle of 45 as will be seen from the Figures. In this case the guide members 29, 30, 31, 32 are also obliquely cut in order to fit to each other in the corner.

FIG. 9 diagrammatically illustrates that the invention may be applied also at a wall structure of concrete in for example apartment buildings, the window openings in the concrete construction being provided with a frame 33 in which the wall plates may be mounted from the outside of the frame and from the inside of the frame principally in the same manner as shown in FIG. 2. Due to this possibility, the wall plates of the standardized shape may be used for single family dwellings as well as for apartment houses.

FIG. 10 illustrates two roof constructions, the left portion showing a roof with roof trusses and the right hand roof construction being provided with roof beams 35.

The roof construction is built of tubular members or sections of substantially the same design as the member 22 in FIG. 6. The roof is divided into a number of module openings which are intended to be covered by outer roof plates and inner roof plates of the same design as used for the wall frame structure. The outer roof plates 36 are fitted into the frame from the outside of the module openings of the outer roof and the inner roof plates 37 are fitted from below into the module openings of the inner roof.

For locking the wall plates to the side members of the frames. as shown in FIG. 12, there is used a locking member denoted generally by the numeral 38. The locking member is shown separately in FIG. 11.

The locking member consists of a hub having a hexagonal throughgoing hole 40 in which a hexagonal sleeve 41 is inserted and serves as a bearing shaft for the locking member. On the hub there is provided a wing or flange 42 extending along a part of a revolution and forming a supporting surface on one of its sides. Upon turning the locking element. this supporting sur' face is intended to cooperate with a stationary supporting surface. In FIG. 12 this supporting surface is formed by the inside of the edge flange 23 in FIG. 12. Because the flange 42 will merely extend along part of a revolution, the locking member will in one of its positions leave a free passage for passing the supporting flange 23 when the wall plate is to be mounted and removed, respectively. The shaft 41 is journalled in the wall plate in cylindrical holes in its structure. Due to the fact that the shaft is hexagonal in cross section, its edges will form contact points with the walls of the holes which will result in that the shaft will not be locked in the bearing hole due to any corrosion.

Because the shaft is formed by a hexagonal sleeve, it can easily be operated by means of an ordinary hexagonal key as will be understood from FIGS. 13-15.

As indicated in FIG. 11 the flange will extend along a helical line along part of the circumference and the rest of the flange will be located in a radial plane. This last portion of the flange is denoted by numeral 43. As will be seen from FIG. 12 this portion 43 of the flange 42 located in the radial plane will be that part which presses against the supporting flange and will then press the flange 12 of the wall plate against the sealing 14. The distance between the flange l2 and the supporting flange 23 will then be fixed to a constant and predetermined distance which is determined by the locking position of the locking member according to FIG. 12. The compression of the sealing 14 can then be chosen to any predetermined and desired value.

The flange 42 has a relatively large width. It will permit a certain relative movement sideways between the frame 13 and the wall plate so that any possible strains in the wall frame structure may be equalized. In FIGS. 13, 14, 15 the locking element is seen towards one side of the structure of the wall plate which is provided with an opening 44 through which the flange of the locking element may be turned out for cooperation with the supporting flange 23. The hexagonal key is denoted by numeral 45.

The sealing 14 in FIG. 12 has a special shape because it is made from a relatively wide ribbon of an elastic material which has such width that it covers the outer sides of the frames in the wall structure as well as in the roof construction. An insulation of the wall structure is thus obtained against changes in humidity and temperature. At its edges the sealing ribbon 14 is formed with longitudinal ridges against which the edge flanges 12 of the plates are resting scalingly. A compression of the ridges of the sealing ribbon 14 provides the required friction pressure between the flange portion 43 of the locking element 38 and the edge flange 23 of the wall structure for maintaining the locking element in its locked position.

in FIGS. 16-25 is shown a particularly suitable coupling for mounting for instance the inner walls. The coupling can be used for other applications.

In FIG. 16 is shown a cross section through a double walled partition wall which is used as a partition wall between two rooms in a building. Two uprights 46 and 47 are secured between the floor and the scaling and are located at a distance from each other in order to leave free space for a displaceable door 48. To the sides of the uprights are coupled inner walls 49, 50, 51, 52. For the sake of simplicity only the coupling of the wall 49 to the upright 46 will be described. The wall plate 49 has a plate 53 which at its end is bent to a flange 54. This flange forms one part of the coupling. The other part of the coupling consists ofa profiled channel at the edge of the upright 46. The walls 55, 56 of the channel are inclined relative one another so that the channel will have a successively reduced width towards its mouth. The mouth opening of the channel is reduced due to the fact that the wall 55 is bent to form an edge flange 57.

Within the conical channel is provided an elastic body 58 which leaves a certain free space adjacent the mouth of the channel for a roller 59 or ball. Between the wall 56 of the channel and the eleastic body 58 is a groove 60.

When the flange 54 is inserted into the mouth 61 of the channel, the flange 54 will press down the ball 59 until it leaves a free passage for the flange 54 between the roller 59 and the wall 56. The flange 54 is pressed down into the groove 60 to a bottom position where the flange compresses the elastic body so that it will provide a certain spring action to press the flange 54 rearwardly. The roller 59 is, however, resting with a certain pressure against the oblique wall 55 and the flange 49 and when the flange 54 is biased to be displaced bacltwards, the roller 59 will form a locking wedge element between the flange 54 and the wall 55 and simultaneously the flange 54 will be pressed against the wall 56. In the right hand portion of FIG. 16 is shown how the flange 54 is in its locked position with the ball 59 in locking position. If the plate 50 shall be removed, this will be made possible by inserting a releasing needle 62 through a hole 63 in the plate 53 of the plate 50, and then the needle will actuate the roller 59 and press it from its locking position. The flange 54 may then be pulled out from the channel.

in FIG. 17 is shown a cross section of a modified embodiment of the coupling for coupling together two walls 64, 65 with sections 66, 67, 68, 69. The plates 64, 65 have a plate and an edge flange 54 in the same man ner as the plates in FIG. 16. However, the difference is that the edge flange 54 is moved into the channel from the opposite side of the same in relation to the device in FIG. 16 which results in that the mouth of the channel will be free when the rollers 59 are in locking position. It will then be possible to reach the lock rollers 59 through the open mouth without it being necessary to provide an additional hole in the manner indicated at 63 in FIG. 16. Instead it will be possible to use a thin roller which is inserted into the opening 70 to press against the rollers 59 so that these will be disengaged from their locking grip and permit that the flange S4 is withdrawn from the channel.

In FIG. 18 is shown another embodiment of the cou pling according to the invention which is located at the lower ends of the two plates. The channel is formed as 7 a section 7l resting against the floor. The locking ofthe flange 54 of the plate 62 will be obtained in the same manner as described in connection with FIGS. I6 and 17. However. the difference is here that the weight of the plate 62 is carried by the flange 54 resting against the horizontal lower part 73 of the channel. The roller 59 is thus completely released from the pressure from the plate 72 and can move freely under the influence of the pressure from the elastic body 58.

In FIG. 19 is shown a modification where two flanges 54a and 54b are inserted into a symmetrical channel 74 with conical walls. Within the channel is provided an elastic body 75 with a groove 76 in the middle for receiving the two flanges located adjacent each other. Between these flanges and the walls of the channel are two lock rollers 59 which provide a locking action as described above. The advantage with this construction is that the transition area 77 between the two plates 78 and 79 will become almost invisible.

In FIGS. 20, 21 is shown a connecting piece adapted to connect two corner portions of two plates 80 and 81 according to FIG. 22. The connecting piece is generally denoted by the numeral 82.

The connecting piece has a T-section and comprises two vertical walls 83, 84 at an angle to each other and forming one side of the channels.

In FIG. the two channels are provided each with an elastic body and a lock roller 59. Into one of the channels is inserted a flange S4 to its locking position. The inclined side walls of the channels are denoted by 85 and 86 on both sides of the vertical wall 83. The in clined side walls of the channels associated with the vertical wall 84 in this portion of the connecting piece are denoted by 87 and 88.

The lock rollers or balls 59 may be of a hard material but the rollers may also be provided with an elastic layer in order to increase the engagement upon lockit FIGS. 23, 24, are shown connecting pieces for elastic bodies 58 and lock rollers 59in conical channels in the same manner as described in connection with the connecting piece according to FIGS. 20 and 21.

In FIG. 23 the connecting piece is intended for coupling together the corners of four plates where the corners are at right angles.

In FIG. 23 is shown a connecting piece which is intended for coupling one corner of a plate with a rightangled corner.

FIG. 25 shows a connecting piece for coupling the corners of three plates together, said corners having an angle of 120 between the side edges of the plate at the corner.

In FIG. 26 is shown a spacer or distance member 89 between two walls 90. 91, which both consist of plates which are coupled together with a distance member by means of coupling of the embodiment described in the preceding Figures. Only one of the channels in FIG. 26 is shown together with the coupling under consider ation for the sake of simplicity.

The elastic bodies 58 shall serve as means for actuating the rollers 59in a direction towards the locking po sition but they also serve as sealing members.

The rollers 59 or corresponding balls may be secured to the elastic body in order to facilitate the mounting of the coupling into the channel.

FIG. 27 shows a device for securing an upright between the floor and the ceiling. the upright being in- 8 tended in its turn to be coupled together with partition walls separating rooms in the building.

The upright is denoted by 90 and is at its lower end rovided with a lifting device which functions by means of a so-called wedging action. In the lower side of the upright is secured a member 91 with a central opening for a stand 93 having a supporting foot. On the bottom side of the member 91 is pivotally secured a lock plate 94 with an oval hole through which the stand 93 is inscrted. By putting the plate into an oblique position is obtained a grip between the edges 95, 96 of the plate against the stand 93. This will prevent a displacement of the plate 94 downwardly on the stand 93 which means that the upright 90 is kept in its position. The lock plate 94 is kept in this locking position by means of the elastic member 97. From this locking position the plate 94 may be tilted by means of a lever 98, which lever 98 presses the plate 94 against the elastic member 97 so that this will be compressed and the plate will re lease its engagement around the stand 93. The upright 90 can then be lowered. The control lever 98 is shown in a position 98A, in which is used for lifting the upright 90. The control lever 98a rests then on the upper end of the stand 93 and in a groove therein. In the stand there are two openings 99. 100 for supporting the control lever 98 and 98a, respectively.

The upper end of the upright 90 is provided with a block 101 of elastic material so that the upright may rest softly against the ceiling with the required friction.

In FIGS. 28 and 29 are shown two modifications of device for securing a window between outer plates and inner plates of the wall construction according to the invention.

In both cases the outer plates are denoted by numeral 102 and the inner plates by 103. Between the plates there is an interspace 104.

In both cases the plates are provided with openings 105 for a window or a door.

In FIG. 28 the window is a displaceable window 106 which is displaceable on supporting member 107 which is secured to one of the wall plates or the wall structure of the building. In the two window openings 105 in the two plates are secured tongue-like sealing ribs 108 of elastic material which rests elastically against the window and seal against the same.

In FIG. 29 is a conventional window frame 109 secured in the window opening of the two plates in a position between the plates for a conventional window or door denoted by 110.

In FIGS. 31-33 are shown modifications of an intermediate member having a plurality of hollow spaces intended to be filled with an insulating material. The intermediate member with its insulating material is then intended to be located between two plates for forming an insulating plate. As will be seen from the Figures, the intermediate member comprises a plurality of plates having six equal sides and being positioned into parallel outer planes and an intermediate plane located between said outer planes.

The plates in one outer plane is denoted by 110 whereas the other plates in the other outer plane are denoted by 111. The plates in the intermediate plane are denoted by 112 in FIG. 30. As will be seen from the Figures. the plates 110 are at every second edge extended with a wall 113 which extends to the other outer plane and is connected to the corresponding side edges of the plates 11] located in this plane. The other sides of the plates 110 extend down to and are connected to the corresponding three edges of the plate 112, and these connecting walls are denoted by 114. The other three edges of the plate 112 are connected to walls 115 which extend down to the three other edges of the plates 1 l I.

In FIG. 30 are shown three cross sections of the intermediate member crossing each other. These cross sections are identical and depending on the shape of the intermediate member. These cross sections will obtain the shape illustrated in FIGS. 32 or 33.

In FIG. 32 the connecting walls 113. 114, 115 are an ranged at right angles to the plates having six equal edges whereas these walls in FIG. 33 are inclined with the result that the six-edged plates will obtain a smaller surface area.

The advantage with the embodiment according to FIG. 32 is that a greater contact surface will be obtained between the side plates of the wall plate and the intermediate member which will result in larger surfaces for gluing. The advantage with the embodiment according to FIG. 33 is among others that this embodiment is relatively simple to press out in metal plate or to mould in plastics.

A common advantage with the two intermediate members according to FIGS. 32 and 33 is that free through-going passages will be obtained in several different directions, for example for forming channels for electric conduits What I claim is:
